One of the objects of the invention resides in the provision of a closet embodying a continuous strip of water resistant combustiblefilm such as sized paper, and mechanism for progressively forming the strip of film into a trough for the reception of fecal matter and urine, and then to fold and flatten it and the contained fecal matter into a thin fiat product susceptible of ready combustion in an incinerator associated therewith.

Another object of the invention is to provide a closet having a support therein for the trough of film before it enters the flattening stage, and to further provide rollers and associated drive means in the closet adjacent the end of the trough support to move the strip of film through the closet, fold and flatten it around the fecal matter carried thereby for entry into an incinerator disposed in contiguous relation with the closet.

Another object of the invention is to provide an incinerator designed to produce a temperature which will effect the complete combustion of the film and fecal matter and urine with dispatch and without emitting of fensive odors.

Another object of the invention is to provide a unit which is relatively small in size, light of weight, and economic of manufacture, which will meet the need of home owners in areas not provided with a sanitation sewer.

Referring first to Figs. 1 and 2, the unit comprises a closet 10 having an incinerator 11 attached thereto and a stack 12 mounted on top of the incinerator to carry off the heat generated therein. The top of the incinerator is formed with an opening 95 for access to the interior thereof. The opening is provided with a cover 96 embodying subtended legs 97 (Figs. 7 and 8) supporting secondary plates 98 in alignment with the inner walls of the incinerator. The closet which may be made of any suitable material, comprises a rectangular body having a depending oval bowl 13, preferably designed to rest on the floor, and an integral square housing 14 protruding from the rearward portion of the body for the reception of the forming rollers, drive gearing, and the adjustment mechanism therefor. As will be seen in Figs. 3 and 4, the interior of the closet is provided with a rectangular frame 15 fulcrumed adjacent the -top thereof upon a shaft 16 mounted in bearing blocks 17 affixed to the inner side Walls of the housing 14.

The frame is inclined downwardly and rests upon a jack screw 18 engaged with the wall of the bowl 13, the sides of the lower end of the frame are provided with brackets 19 drilled .and reamed to support a pair of shafts carrying flanged rollers 20 and 21 spaced to support arch of paper 22, or a film of a similar character. The shafts are designed for axial adjustment in the brackets, and may be locked in position by set screws mounted in the brackets. The rollers idle on the shafts and are spring pressed against nuts affixed to the ends of the shafts. The central portion of the frame 15 supports a strut 15a, which in turn, supports a downwardly inclined triangular plate 23 having side walls 24 extending upwardly from near the apex of the triangle to the base thereof. The top of the plate 23 is disposed within the forward end of the bowl 13 and is formed with a horizontal rolled edge 25, while the lower ends of the upturned side walls are vertical and terminate in front of the opening between a pair of spaced rollers 26. Adjacent the ends of the rolled edge. 25 there are provided shoes bent to deflect the paper 28 within the side walls 24. When the strip of paper or film 28 is brought from the supply roll 22 over the rolled edge 25 of the plate 23, and the edges deflected upward by the shoes 30, thence folded vertically and passed between the spaced rollers 26, a triangular shaped trough of paper or fihnis formed over and within the plate 23 and the converging side walls 24 for the reception of fecal matter and urine. The circumferential faces of the rollers 26 are crossknurled to grip and draw the paper, together with the fecal matter carried thereby, between the rollers during the rotative cycle thereof.

The rollers 26, (Figs. 5 and 6) are hollow and counterbored to receive end plates 31 which are bored for running clearance on shafts 32 affixed in and depending from bell cranks 33 and 34 mounted on the shafts 16. The bell crank 33 is drilled and tapped to receive a screw 35 bored for sliding engagement on the shaft 16, and a sleeve 36 is mounted on the shaft in abutting engagernent with a boss 37 on the inner face of the frame 15. Lateral movement of the bell crank and the roller supported thereby is attained by adjustment of the screw 35. The bell crank 34 is drilled to receive a bushing 38 mounted for free rotational movement on the shaft 16, and a second sleeve similar to the sleeve 36 is mounted on the shaft 16 in abutting engagement with the bushing 38. The inner arm 39 (Fig. 6) of the bell crank 34 is machined for the rota'tive support of a shaft 40, the

is mounted in the outer end of the arm 44 to delimit the movement of the pawl 45 upon retraction of the arm 41. The outer leg 47 of the bell crank 34 is bored for the reception of a pin 49 having an eccentric pintle 48 therein which supports a sheave 50, and a belt 51 is roved over the pulley and sheave, the central portion of the lower run thereof being impinged between the paper film 28 and the walls of the upper ends of the rollers 26. The pin 49 is locked in position by a set screw 52, but the sheave may be adjusted to align the belt into parallel relation with the ends of the rollers by loosening the screw and adjusting the pin 49. Both the bell cranks 33 and 34 are formed with integral upward and outwardly directed arms 53 having slots in the outer ends thereof to receive lock screws threaded in the ends of bolts 54. The bolts are threaded in bosses 55 in the cross member of the frame 15 and abut washers 56 on the arms 53, thus facilitating rocking adjustment of the bell cranks about their fulcrums on the shaft 16. The cross member of the frame 15 is further provided with a bracket 57 for the support of a sheave wheel 58 engaged with the belt 51 which is adapted to vary the tension thereon upon adjustment of the bracket 57 and holding it in place by means of bolts 55a.

The operative adjustment of the mechanism is attained by rocking the bell crank until the proper position of the rollers axes in relation to the run of the paper is attained, the locking the arms 53 of the bell cranks against the bolts 54 by adjustment of the screws 54w. Lateral pressure on the belt 51 is attained by the adjustment of the screw 35.

The edges of the folded strip of film are compressively engaged on either side of the belt and the top portions of the rollers. With the rearward translation of the belt, the strip of film is drawn from the supply roll across the plate, and the folded strip with the fecal matter carried thereby will be rolled into a relatively flat thin product suitable for burning with an economy of fuel.

As illustrated in Figs. 1, 2 and 3, the top of the closet 10 is provided with a cover plate 65 conforming to the lineation of the bowl and housing, and formed with depending oval flange 59 superjacent the forward end portion of the inclined plate 23. The top of the remaining portion of the cover plate is formed with an outer depending flange 60 which conforms with the top of the bowl and forms a housing for the pulley 43 and the mechanism associated therewith. The cover is held in place by lugs 61 aflixed within the bowl in the corners thereof and protruding upwardly to arrest lateral movement of the flange 66. The cover plate is provided with a toilet seat 62 of conventional form, hinged adjacent the rear end thereof, the opening in the seat being aligned vertically over the trough of film heretofor described.

Referring now to Figs. 1, 2, 7, 9 and 11, the closet 10 is attached to the incinerator 11 through a rectangular sheet metal breeching B, having a valve therein comprising a fixed plate 63 padded with a soft heat resisting material, and a second reciprocative plate 64 designed to close the opening in the incinerator that communicates with the closet. The padding on the plates 63 and 64 is provided with grooves 66 adjacent the lower ends thereof to accommodate the fiow of liquids to an evaporating pan 67 forward the burner nozzle 34!) in the base of the combustion chamber 69. The padding on the plates 63 and 64 is impregnated with flame inhibiting chemicals of any well known form to extinguish the flame which might work back from the combustion chamber.

The plate 64 is actuated by a bar 70 supported for reciprocative movement in guide straps 71 mounted on an outer side wall of the incinerator. The incinerator is formed with a sheet metal housing that surrounds the incinerator assembly. The bar 70 is secured to the valve plate 64 and is pivotally connected, adjacent its outer end, through a slotted hole, to a lever 73 fulcrumed in the center thereof to the side wall of the housing. The upper end of the lever 73 is provided with an open socket 74 disposed at an angle of approximately fifteen degrees (15) to the major axis thereof. The

socket receives a rod 75 mounted in a collar 76 on the flanged hub 72 which is keyed to the shaft 40, and a delayed movement of the hub 72 is provided by a pin 77 seated in the flanged hub which protrudes into an arcuate slot 78 in the collar, of approximately twelve degrees (12) in length. The collar is restrained against axial movement by a snap ring 76a seated in a groove in the hub. The collar assembly is normally held in full line position, as illustrated, by-a spring 80 anchored to the collar 76, and, to the floor. In operation, the crank arm 41 travels from its full line position to the dotted line 81 before the shoulder defined by the slot 78 reaches the pin 77. As this occurs, the rod 75 will rock the lever 73. as it ascends in theangularly disposed socket 74 and open the valve 64. Continued movement of the arm 41 to the dotted line position 82 will eflfect the rotation of the rollers 26 and the passage of the folded film and the flattened fecal matter contained therein into the combustion chamber. The spring 80 will effect the return movement of the arm 41 to the closed position of the valve plate 64.

The flame generating mechanism of the incinerator is the conventional type comprising a blower 83 and fuel pump 89 both driven by the motor 113. The blower compresses the air within the housing 83a from whence it is discharged through perforations in the cone 84a surrounding the fuel nozzle 84b which is at the end of the fuel line 84. An ignitor 91 ignites the mixture of air and fuel producing a flame which is projected into the combustion. chamber 69 and the exhaust conduit 86 by the combined action of air velocity and the combustion of the fuel. A removable evaporating pan 67, having a beveled edge 87 forms the top of the horizontal portion of the conduit 86 and is adapted to receive liquids which drain through the narrow U shaped channel formed when the film is folded between the rollers. The folded strip of film enters the combustion chamber 69 through the port 79 which is a continuation of the breeching B. A grid 88 is placed in the combustion chamber to prevent the folded strip of film from falling over and obstructing the path of the flame into the exhaust conduit 86. In operation, about one-third of the fiarne sweeps across the top of the pan igniting and consuming the folded strip of film and the thin section of fecal matter which it carries. The smoke, steam and other products of combustion travel downward and are drawn into that portion of the flame which enters the exhaust conduit directly from the burner and are consumed by the high heat of this flame so that odors in the final exhaust are eliminated.

The shell of the combustion chamber is surrounded essert by a second shell 85a providing an insulating air passageway which receives air from the housing 83a through the opening 92 and discharge it through the opening 92a into the stack 12 which surrounds the exhaust conduit 86. The assembly of parts of the incinerator as described, are enclosed in a housing 11 which number is also used to designate the incinerator as a unit.

From the foregoing, it will be seen that the folded strip of film will support the fecal matter and urine which may be deposited thereon, that the rollers will extrude the folded film and contained fecalmater into a thin, flat product, and that the flame from the burner in the incinerator will effect the ready and complete combustion of the film and fecal matter and urine without emitting offensive odors.

Referring to Fig. 13, the blower 83, fuel pump 89, valve 90 therefore and the lighter or ignition device 91 are automatically controlled through an electric timer 100 actuated by a starting switch actuated by the hand lever 41. As will be seen in Fig. 9, the end of the bar 7t) is arranged to abut the stem of the switch 101, which is normally held in its open position by a spring. When the switch is closed, current from the power line 104 will flow through the line 1%, the switch 101, the timing motor 106 and to the ground line 7, thus exciting the motor and initiating the rotation of a sweep arm 1% in the timer 190. The sweep arm 1% is formed with a broad land 113 on the free end thereof. As the land 118 leaves the switch 119, it is closed under the influence of a spring therein, current from the line 104 n will flow through the line 110, switch 119, and an extension of the line 1% to the timing motor 106, thence to the ground line 1197. Such action assures the continued operation of the timer. When the sweep arm reaches the switch 109, the plunger therein will be actuated to close the circuit through the lines 104, 110, 111 and 112 to the motor 113 for the blower 83, fuel pump 89 and ignition device 91 and thence to the ground line 107. When the arm 108 reaches the spring pressed switch 115, current from the line 1M will flow through the line 11o, the switch 115, and the continuation of the line 116 to a solenoid 117 for the fuel valve 90. This valve is normally held in its closed position by a spring, but it held open by the solenoid 17 while the current flows through line 116, the solenoid, and the continuation of the line 116 to the ground line 107. The land 11% further maintains the switch 115 in its closed position for a normally sufficient period to sustain the flame. Thevalve stern rod 114 for the valve switch 120, is formed of an expandable material which is disposed in the path of the flame from the burner. When the valve stem rod is heated and expanded, the switch 120 is closed and the current will flow through the lines 104, 130, switch 122 and line 121, the switch 120 and the lines 121 and 116, thus holding the solenoid 117 for the valve 90 in an open position.

In the event the flame goes out in the incinerator, the rod 114 in the switch 120 will contact and open the circuit to the solenoid valve 117, thus breaking the circuit from the lines 104, 130, switches 122, 120 to the line 121, thus shutting ofi": the fuel. T he circuit through the switch 115 has by this time been broken by the movement of the sweep arm 108. When the flame is burning, as in normal operation, with the switch 120 closed, the continued movement of the sweep arm 103 will engage and open a spring pressed switch 122, thus breaking the circuit which has been holding the solenoid 117 open and causing the valve operated thereby to close under the influence of the spring therein. not be reactivated during the cycle, since the rod 114 contracts when, the flame goes out and breaks the circuit in the switch 120. When the arm reaches the switch 123 which is held open by a spring therein, the solenoid 124 The solenoid 117 can cuit to the motor for the blower 83, fuel pump 89 and ignitor 91. Current from the line 104 will, however, flow through the line 110, the switch 119, the line to the timer motor 106 which continues to run until the sweep arm 108 reaches the switch 119 and breaks the current to the line 105.

The switches 122 and 123, which stops the burning action of the fuel, are mounted on a carriage 131, rotatable from a center common to the sweep arm 108. Movement of the carriage 131 varies the timing cycle of combustion of the fuel.

The evaporating pan 67, which is electrically insulated from the body of incinerator, is provided with a fluid switch, comprising a pair of spaced terminals 125 defining a gap 126 which is closed when the fluid bridges the gap. 7 When the gap is closed, the current flows from the line 104 through the line 105 and the switch gap 126, thence to the motor 106 and ground line 107, thereby starting the time cycle as previously described.

Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not intended to be restrictive or confining, and that various rearrangements of parts and modifications of detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
